    [0002] Composition to increase the density of liquids
    [0004] Technical field of the invention
    [0006] The present invention relates to the field of the chemical industry and, more particularly, to the development of a new composition with suitable properties to increase the density of liquids. The invention also relates to multiple applications of the new composition, both in industry in general, and for use in wind turbines located in the offshore sea or located on land.
    [0008] State of the art prior to the invention
    [0010] As the closest antecedent to the present application, various chlorides can be mentioned (such as sodium chloride, magnesium chloride or zinc chloride) which, among their multiple properties, allow to increase the density of liquids, but have the problem of being very corrosive and oxidizing. For this reason, the use of this type of compound is not suitable for many of the applications of industrial use.
    [0012] Thus, the present invention arises as a solution to the problems derived from the compositions of the state of the art based on the use of chlorides as the main ingredient of the formulation. It is, therefore, a new formula that has proven to be especially effective in increasing the density of liquids and, especially, water, without entailing the harmful, corrosive and oxidizing or unwanted effects of chlorides.
    [0014] Detailed description of the invention
    [0016] The present invention therefore refers to a new composition suitable for increasing the density of water, characterized in that it comprises, in percentage by weight:
    [0018] - potassium citrate, in a percentage between 1.2 and 63%;
    [0019] - sodium citrate, in a percentage comprised between 1.5 and 66%;
    [0020] - monoethylene glycol, in a percentage comprised between 2.2 and 97%;
    [0021] - monopropylene glycol, in a percentage comprised between 5.1 and 94%; Y
    [0022] - azoles in a percentage between 1.03 and 22%.
    [0024] In an especially preferred embodiment of the invention, the composition is characterized in that it comprises, in percentage by weight:
    [0026] - potassium citrate, in a percentage of 50%;
    [0027] - sodium citrate, in a percentage of 10%;
    [0028] - monoethylene glycol, in a percentage of 30%;
    [0029] - monopropylene glycol, in a percentage of 7%; Y
    [0030] - azoles in a percentage of 3%.
    [0032] All the components of the formula object of the invention have the advantage of being respectful with the environment. Therefore, they are components that do not present any type of toxicity in small quantities and are not corrosive or oxidizing.
    [0033] Another object of the invention is the use of the composition to increase the density of liquids, and particularly water. Thanks to the use of the claimed composition, it is possible to increase the density of the water until reaching a density greater than 1 g / l at room temperature (25 ° C).
    [0035] The chemically modified water object of the invention has the advantage of being able to be used in many different industrial applications. This represents an important advantage over other alternative formulations of the state of the art.
    [0037] As mentioned above, unlike other known compositions for increasing the density of water, the present formulation does not present any type of harmful effect on human health.
    [0039] Likewise, as a consequence of the presence of salts in the water, it is possible to avoid the development of microorganisms or other contaminating substances in it. This supposes an additional advantage since, in this way, the use of chemical decontaminating substances is avoided, which often imply problems of contamination of the waters in which they are applied. Thanks to the ingredients that make up the composition, it is especially suitable to withstand low temperatures (for example, temperatures between -10 ° C and -28 ° C) without freezing.
    [0041] Description of an embodiment of the invention
    [0043] In order to test the advantages of the formulation object of the invention, a test was carried out for which a formulation was prepared according to the especially preferred composition that has been described in the previous section. In particular, a formulation was prepared characterized by comprising, in percentage by weight:
    [0045] - potassium citrate, in a percentage of 50%;
    [0046] - sodium citrate, in a percentage of 10%;
    [0047] - monoethylene glycol, in a percentage of 30%;
    [0048] - monopropylene glycol, in a percentage of 7%; Y
    [0049] - azoles in a percentage of 3%.
    [0051] This formulation was added to a volume of 1 liter of water. Next, the salts were mixed at room temperature (25 ° C), subjecting the mixture to stirring until a homogeneous mixture was achieved. No freezing was observed at low temperatures (between -10 ° C and -28 ° C).
    [0053] Subsequently, a buoyancy test was carried out by introducing a heavy object in the chemically modified water, which floated on the surface of the water, thus demonstrating the increase in the density of the water by using the composition object of the invention (up to values between 1.42 and 1.7 g / l at 25 ° C).
    [0055] A very relevant application of the claimed composition is its use in wind turbines to damp the frequencies of the wind of wind turbines located both on land and offshore, in which case they also allow to dampen the waves of the sea.
    [0056] Preferably, potassium citrate may be used in the composition in a percentage comprised between 10% and 50% by weight, and more preferably between 25% and 50%. in weigh. In particular embodiments of the invention, the additive E-332 with a density of 1.98 g / cm3 at a temperature of 25 ° C may be used as potassium citrate.
    [0057] In other particular embodiments of the invention, the additive E-331 may be used as sodium citrate with a density of 1.70 g / cm3 at a temperature of 25 ° C, preferably in a percentage by weight of between 10% and 30%. by weight, and more preferably between 25% and 30%. Additionally, the composition may comprise other compounds, such as, for example, corrosion inhibitors and / or glycols.
    [0058] The compounds used in the formulation are characterized by having a density that can vary, at room temperature (25 ° C), between 1 g / cm3 and 1.98 g / cm3 in the case of potassium citrate, between 1 and 1.7 g / cm3 , in the case of sodium citrate and between 1.2 and 1.3 g / cm3 in the case of monoethylene glycol and monopropylene glycol.
    [0059] Additionally, the azoles used in the composition have the advantage of inhibiting corrosion.
    [0060] As a consequence of the properties of the claimed formula, an especially preferred application of the same will be its use in wind turbines located both in the offshore sea and on land, to dampen the oscillations of the wind and waves of the sea.
